Artillery Weapons of Art #1

All human art and creativity comes from an ancient power source, amplified by magical gateways all over the world, but now a sentient AI is closing the gateways in order to control all of the world's creative arts. As humanity loses the ability to create art, the last gateway brings the Mona Lisa to life so she can form a team of artists to steal the gateway of creativity back from the AI. Three artists are given magical abilities that transform their art into weapons: a graffiti artist, a film FX artist, and a comic book artist. Together they plan an elaborate heist to save the last gateway of creativity.
